Warning: Spoilers follow for all of HBO’s Game of Thrones through Season 8 Episode 4 “The Last of the Starks.” A few book spoilers follow as well, with regards to who’s still alive at the end of A Dance with Dragons.
Ever since Season 6, HBO’s Game of Thrones has been untethered from George R. R. Martin’s book series, having passed the author’s Song of Ice and Fire saga while Martin continuously works to finish the (presumed) penultimate book in the series, The Winds of Winter. Needless to say, many characters have died on the show since then – many of whom were still alive by the end of A Dance with Dragons and may even survive all of TWOW and make it to the entire adventure’s endgame.
